I’m posting about the nasty problem where no matter what you post it says “server error”.

Yeah.

So I reinstalled, and that didn’t work, but then I deleted the preferences file file (kind of a pain, you have to redo your toolbar, etc.) and suddenly it worked again.

The file I deleted is in users>you>library>preferences>com.warped.iJournal.plist

I don’t know if this will work for everyone, but I think it’s worth a try, especially if nothing else works.
